DESCRIPTION OF THE PREFERRED EMBODIMENTS

A component mounting device according to an embodiment of the presentinvention will be described with reference to FIG. 1. The componentmounting device 1 has a function of mounting a component 3 on asubstrate 2. Hereinafter, an X direction, a Y direction, and Z directionare defined as a conveying direction horizontal to the substrate 2, adirection orthogonal to the X direction in a horizontal plane, and adirection perpendicular to the XY plane, respectively.

A component supply unit 6 supplying the component 3 is disposed on anupper surface of a base 4 included in the component mounting device 1.The component supply unit 6 includes a first supply unit 6 a supplying aradial lead component, a second supply unit 6 b supplying an axial leadcomponent, and a third supply unit 6 c supplying a chip component. Theradial lead component is a component having a lead (first lead)projecting downward from a lower portion of a body. The axial leadcomponent is a component having a lead (second lead) projectinglaterally from both sides of a body with a tip bent downward. The firstsupply unit 6 a, the second supply unit 6 b, and the third supply unit 6c are disposed in parallel in the X direction. The component supply unit6 supplies the component 3 by a parts feeder 10 such as a radial feeder,an axial feeder, or a tape feeder.

Y-axis beams 14 are disposed at both ends of the base 4 in the Xdirection and the Y-axis beams 14 are provided with an X-axis beam 15movable in the Y direction. A plate-shaped plate member 16 is attachedto the X-axis beam 15 slidably in the X direction, and a mounting head17 is attached to the plate member 16. By driving the X-axis beam 15 andthe plate member 16, the mounting head 17 can be moved in the X and Ydirections. The mounting head 17 has a function of taking out andmounting the component 3 from the component supply unit 6 onto thesubstrate 2.

The base 4 is provided with a component recognition camera 19 having animaging field of view facing upward and an adapter stocker 20 betweenthe substrate 2 and the component supply unit 6. The componentrecognition camera 19 takes an image of the component 3 held by themounting head 17 moving above the camera from below. The adapter stocker20 stores an adapter 50 (FIGS. 14A and 14B) described later.

A configuration of the mounting head 17 will be described with referenceto FIG. 2. The mounting head 17 is made up of multiple (in this case,three) unit heads 17A, 17B, 17C. The unit heads 17A, 17B are eachconfigured to include a head body 21 and a suction nozzle 22 attached toa lower end portion of the head body 21. The head body 21 has a rotarymechanism (not shown) rotating the suction nozzle 22 in the horizontaldirection etc. built-in. The suction nozzle 22 is moved in the Zdirection, i.e., raised/lowered, by a nozzle raising/lowering mechanism23 disposed on the upper side of the head body 21. The suction nozzle 22sucks and thereby holds the component 3 supplied from the componentsupply unit 6 and transports and mount the component onto the substrate2. Although the mounting head 17 is made up of the multiple unit heads17A, 17B, 17C in this description, the mounting head may be made up ofthe only one unit head 17C.

A configuration of the unit head 17C will be described with reference toFIG. 3. The unit head 17C includes a head body 24, a chuck unit 25mounted rotatably in the horizontal direction around the verticaldirection (Z direction) on the lower side of the head body 24, and ahead raising/lowering mechanism 26 disposed on the upper side of thehead body 24. The head raising/lowering mechanism 26 includes araising/lowering motor 261, a feed screw 262 connected to theraising/lowering motor 261, and a nut part 263 screwed to the feed screw262 and fixed to the head body 24. The head raising/lowering mechanism26 rotates the feed screw 262 through driving of the raising/loweringmotor 261 to move the nut part 263 so that the head body 24 is moved inthe Z direction, i.e., raised/lowered.

The head body 24 is provided with a chuck driving motor 241 driving thechuck unit 25, a chuck rotating motor 242 rotating the chuck unit 25 inthe horizontal direction, and a pusher device 243. The pusher device 243includes a pusher 44 and a pusher actuator 45. The pusher 44 is moved inthe Z direction, i.e., raised/lowered, by the pusher actuator 45 and islowered to the component 3 clamped by the chuck unit 25 to push down thecomponent 3.

The chuck unit 25 includes a raising/lowering rod 251. An upper endportion of the raising/lowering rod 251 is connected to the chuckdriving motor 241 via a speed reduction mechanism made up of a wormwheel 241 a and a worm gear 241 b. When the chuck driving motor 241rotates the worm gear 241 b, the worm wheel 241 a meshed with the wormgear 241 b swings so that the raising/lowering rod 251 coupled to theworm wheel 241 a is moved in the Z direction, i.e., raised/lowered.

A configuration of the chuck unit 25 will be described with reference toFIGS. 4 to 7B. FIG. 5 is a view on arrow V of FIG. 4, and FIG. 6 is aview on arrow VI of FIG. 4. The chuck unit 25 has a pair of chuck jaws39 (39 a, 39 b) gripping the component 3. The chuck jaw 39 a and thechuck jaw 39 b are connected to the raising/lowering rod 251 throughrespective separate members. By raising/lowering the raising/loweringrod 251, the chuck jaws 39 a, 39 b are moved closer to or away from eachother. A connection structure between the raising/lowering rod 251 andthe chuck jaws 39 a, 39 b will hereinafter be described in more detail.As described above, the chuck unit 25 can be rotated in the horizontaldirection by the chuck rotating motor 242. However, it is assumed forconvenience that the clamping direction of the component 3 of the chuckunit 25 is set to the X direction while the direction orthogonal to theclamping direction is set to the Y direction in a horizontal plane inthis description.

One end portion of a lever 92 a is connected via a roller 91 a to oneside of a lower end portion of the raising/lowering rod 251. The roller91 a is disposed movably in the X direction relative to theraising/lowering rod 251. By raising/lowering the raising/lowering rod251, the lever 92 a is allowed to pivot around a lever support shaft 93a. The other end portion of the lever 92 a is connected to a slide part95 a via a roller 94 a, and the slide part 95 a can slide in the Xdirection as the lever 92 a pivots. The slide part 95 a is engaged witha rail 97 a attached to an inner surface of a frame 252 via a slideblock 96 a and slides in the X direction along the rail 97 a.

Particularly, as shown in FIGS. 7A and 7B, a jaw attachment seat 98 a isfixed to the slide part 95 a, and the chuck jaw 39 a is attached to thejaw attachment seat 98 a with screws 99 a. Therefore, when the slidepart 95 a slides, the chuck jaw 39 a moves in the direction of slidingof the slide part 95 a.

On the other hand, one end portion of a lever 92 b is connected via aroller 91 b to the other side of the lower end portion of theraising/lowering rod 251. The roller 91 b is disposed movably in the Xdirection relative to the raising/lowering rod 251. By raising/loweringthe raising/lowering rod 251, the lever 92 a is allowed to pivot arounda lever support shaft 93 b. The other end portion of the lever 92 b isconnected to a slide part 95 b, and the slide part 95 b can slide in theX direction as the lever 92 b pivots. The slide part 95 b is engagedwith a rail 97 b attached to an inner surface of a frame 252 via a slideblock 96 b and slides in the X direction along the rail 97 b.

Particularly, as shown in FIGS. 7A and 7B, a jaw attachment seat 98 b isfixed to the slide part 95 b, and the chuck jaw 39 b is attached to thejaw attachment seat 98 b with screws 99 b. Therefore, when the slidepart 95 b slides, the chuck jaw 39 b moves in the direction of slidingof the slide part 95 b.

Particularly as shown in FIGS. 5 and 6, since the rail 97 a and the rail97 b are oppositely disposed away from each other in the Y direction onthe inner surface of the frame 252, the slide part 95 a sliding alongthe rail 97 a and the slide part 95 b sliding along the rail 97 b do notinterfere with each other. The chuck jaw 39 a and the chuck jaw 39 b areadjusted in positions in the Y direction by the jaw attachment seat 98 aand the jaw attachment seat 98 b and are arranged at positions facingeach other in the X direction.

The movement of the chuck jaws 39 a, 39 b will hereinafter be describedwith reference to FIGS. 4, 8, and 9. FIG. 4 shows a state in which theraising/lowering rod 251 is located at a highest position. When theraising/lowering rod 251 is located at the highest position, the chuckjaw 39 a and the chuck jaw 39 b are most distant from each other. Whenthe raising/lowering rod 251 is lowered as shown in FIG. 8, the rollers91 a, 91 b are accordingly lowered and further moved in an X1 direction.As the rollers 91 a, 91 b are moved, the lever 92 a pivots around thelever support shaft 93 a, and the lever 92 b pivots around the leversupport shaft 93 b. As the lever 92 a pivots, the slide part 95 a slidesin the X1 direction via the roller 94 a. Similarly, as the lever 92 bpivots, the slide part 95 b slides in an X2 direction via the roller 94b. Due to the movement of the slide parts 95 a, 95 b, the chuck jaws 39a, 39 b move closer to each other.

When the raising/lowering rod 251 is further lowered to a lowestposition, as shown in FIG. 9, the rollers 91 a, 91 b are lowered andfurther moved in the X2 direction. The levers 92 a, 92 b accordinglypivot and, as the levers 92 a, 92 b pivot, the slide parts 95 a, 95 brespectively slide in the X1 and X2 directions. Due to the movement ofthe slide parts 95 a, 95 b, the chuck jaws 39 a, 39 b abut each other.Usually, before the chuck jaws 39 a, 39 b abut each other, i.e., beforethe raising/lowering rod 251 is lowered to the lowest position, thechuck jaws 39 a, 39 b clamp the component 3.

The chuck jaws 39 are used for chucking (clamping) the component 3 andare made of metal resistant to abrasion. In FIGS. 10A and 10B, the chuckjaws 39 are each configured to include a substantially L-shaped baseportion 41 and a jaw portion 42 extending in the vertical direction fromthe lower side of the base portion 41. Multiple hole portions 41 a areformed in the base portion 41, and the screws 99 a, 99 b are screwedthrough the hole portions 41 a into screw holes of the jaw attachmentseats 98 a, 98 b.

A locking groove 42 a is formed on a surface of the chuck jaw 39 on theside opposite to a clamping surface 40. The locking groove 42 a is usedwhen an adapter 50 described later is attached.

The clamping surface 40 of the chuck jaw 39 has a holding groove 90 cformed for holding a lead of an axial lead component. The holding groove40 c extends toward a tip of the chuck jaw 39 to guide the lead towardthe substrate 2.

Description will be made of clamping of a component (first component) 31and a mounting operation onto the substrate 2 with the chuck unit 25when the component 3 is a radial lead component with reference to FIGS.11A and 11B. The operation described below is implemented by a controlpart 70 (FIG. 24) of the component mounting device 1 controlling variousmechanisms including a drive motor 37. As shown in FIG. 11A, thecomponent 31 serving as a work object of the chuck unit 25 is a radiallead component including a pair of leads (first leads) 3 b on a lowersurface of a body (first body) 3 a and is supplied by the first supplyunit 6 a. The first supply unit 6 a includes a conveying chute 11conveying the component 31 to a supply position for the chuck unit 25while supporting the lower surface of the body 3 a, and the component 31is supplied while being supported by the conveying chute 11.

First, as shown in FIG. 11A, a pair of the chuck jaws 39 ispreliminarily moved in directions away from each other (see the chuckjaws 39 indicated by broken lines) and is lowered to the component 31 onthe conveying chute 11 to enclose the body 3 a from both sides. The pairof the chuck jaws 39 then move in directions approaching each other(arrows e) to pinch the body 3 a. As a result, the pair of the chuckjaws 39 clamps the component 31. Therefore, the pair of the chuck jaws39 is a pair of clamping members pinching and clamping the component 31.

Subsequently, the pair of the chuck jaws 39 clamping the component 31 ismoved to above the substrate 2 preliminarily positioned at a workposition. As shown in FIG. 11B, the pair of the chuck jaws 39 is loweredtoward the substrate 2 to bring the lower surface of the body 3 a intocontact with the substrate 2 while inserting the leads 3 b into openings2 a formed in the substrate 2. The pair of the chuck jaws 39 then movesin directions away from each other (arrows f) to release the clamping ofthe component 31. The pusher 44 is then lowered (arrow g) to push thecomponent 31 against the substrate 2. Subsequently, the leads 3 b areclinched by a clinching mechanism (not shown). As a result, thecomponent 31 is mounted on the substrate 2.

Description will be made of clamping of a component (second component)32 and a mounting operation onto the substrate 2 with the chuck unit 25when the component 3 is an axial lead component with reference to FIGS.12A to 13B. The operation described below is implemented by the controlpart 70 (FIG. 24) of the component mounting device 1 controlling variousmechanisms including the drive motor 37. As shown in FIG. 12A, thecomponent 32 serving as a work object of the chuck unit 25 is acomponent including leads (second leads) 3 d projecting laterally fromboth sides of a body (second body) 3 c with a tip bent downward and issupplied by the parts feeder 10. The conveying chute 11 is provided witha support portion supporting the body 3 c, and the body 3 c is supportedby the support portion so that the component 32 is held in theconveyance chute 11. The component 32 is supplied by the parts feeder 10in this state.

First, as shown in FIG. 12A, an interval D2 of the pair of the chuckjaws 39 is set according to an interval D1 between the leads 3 d. Thechuck unit 25 is then lowered toward the component 32. As shown in FIG.12B, the leads 3 d are inserted between the chuck jaws 39 by the partsfeeder 10 and the leads 3 d are held in the holding grooves 40 c so thatthe component 32 is clamped by the chuck jaws 39. The chuck unit 25 isthen raised by the head raising/lowering mechanism 26 and the component32 is lifted from the conveying chute 11 while the chuck jaws 39 areclamping the component 32.

Subsequently, as shown in FIG. 13A, the pair of the chuck jaws 39 in astate of clamping the component 3 is moved to above the substrate 2preliminarily positioned at a work position. The pair of the chuck jaws39 is lowered toward the substrate 2 to bring the lower surface of thebody 3 c into contact with the substrate 2 while inserting the leads 3 dinto the openings 2 a formed in the substrate 2. The pair of the chuckjaws 39 is moved upward to release the clamping of the component 32. Asshown in FIG. 13B, the pusher 44 is then lowered (arrow g) to push thecomponent 32 against the substrate 2. Subsequently, the leads 3 d areclinched by the clinching mechanism (not shown). As a result, thecomponent 32 is mounted on the substrate 2.

The adapter 50 detachably attached to the chuck jaw 39 will be describedwith reference to FIGS. 14A to 17B. The adapter 50 is used for clampingthe component 3 in place of the chuck jaw 39 and configured to include aflange part 51 and a clamping part 52 disposed under the flange part 51.The flange part 51 is a substantially H-shaped member having notchportions 51 a respectively formed at both ends in the longitudinaldirection. The notch portions 51 a are used when the adapter 50 isstored in the adapter stocker 20 described later. An opening portion 51b opened in the vertical direction is formed substantially at the centerof the flange portion 51 in a planar view so as to insert the chuck jaw39 in the longitudinal direction. The opening portion 51 b is set to asize corresponding to the jaw portion 42 of the chuck jaw 39 viewed inthe longitudinal direction.

In FIG. 15A, the clamping part 52 is mainly made up of a block member 53having a polyhedral structure and has one side surface formed intomultiple stages. The block member 53 has a first opening portion 53 aformed by opening an upper surface in communication with the openingportion 51 b of the flange part 51. The first opening portion 53 a isalso set to a size corresponding to the jaw portion 42 of the chuck jaw39 viewed in the longitudinal direction so that the opening portion 51 band the first opening portion 53 a form one opening portion continuouslyin the vertical direction. Therefore, the adapter 50 has an openingportion (the opening portion 51 b, the first opening portion 53 a) withan upper surface opened. A second opening portion 53 b is formed on theupper side of one side surface of the block member 53 in communicationwith the first opening portion 53 a. As shown in FIG. 15B, when the jawportion 42 is inserted into a deep portion of the block member 53, thelocking groove 42 a is exposed through the second opening portion 53 b.

On the one side surface of the block member 53, a groove 53 c forattaching a flat spring member 54 is formed to extend in the verticaldirection at a position below the second opening portion 53 b. A screwhole 53 d is formed at a position corresponding to the groove 53 c and ascrew 55 is screwed into the screw hole 53 d through a hole portion 54 aformed in the flat spring member 54 so that the flat spring member 54 isattached to the block member 53 (FIG. 14A).

The flat spring member 54 is a rectangular flat plate-shaped elasticbody extending to the position corresponding to the second openingportion 53 b. An upper end portion of the flat spring member 54 is afree end and has a bent portion 54 b formed at a position correspondingto the second opening portion 53 b and bent toward the inside of theblock member 53. While no external force acts on the flat spring member54, a portion of the bent portion 54 b passes through the second openingportion 53 b and further enters the first opening portion 53 a.

Another side surface of the block member 53 opposite to the one sidesurface with the second opening portion 53 b formed is a surfacecorresponding to the clamping surface 40 a of the chuck jaw 39 and is aclamping surface 40 b clamping the component 3. The clamping surface 40a of the chuck jaw 39 clamping the component 3 and the clamping surface40 b of the adapter 50 clamping the component 3 are different in shapeand size. Specifically, the adapter 50 has the clamping surface 40 barbitrarily designed in terms of shape and size depending on the shape,size, weight, etc. of the component 3 that is the work object. Byattaching the adapter 50 having the clamping surface 40 b correspondingto the shape/size of the component 3 to the chuck jaw 39, various typesof the components 3 can stably be clamped. In this embodiment, asheet-shaped member 56 acquired by forming an elastic member of urethanerubber etc. into a sheet shape is affixed to the clamping surface 40 bof the block member 53. The sheet-shaped member 56 is formed into ashape corresponding to the clamping surface 40 b. When the component 3is clamped, the sheet-shaped member 56 comes in contact with thecomponent 3 so as not to damage the component 3. The sheet member 56 maynot be included.

A form of attaching the adapter 50 to the chuck jaw 39 will be describedwith reference to FIGS. 17A and 17B. FIGS. 17A and 17B showcross-sectional views of the adapter 50 and the chuck jaw 39. First, thechuck jaw 39 is inserted into the opening portion 51 b of the flangepart 51 from the tip portion. As shown in FIG. 17A, in the process ofallowing the jaw portion 42 of the chuck jaw 39 to pass through thefirst opening portion 53 a of the block member 53, the bent portion 54 bis pushed in the direction opposite to the bending direction by asurface of the jaw portion 42 (portion in which the engaging groove 42 ais not formed). Subsequently, as shown in FIG. 17B, at the timing whenthe locking groove 42 a of the jaw portion 42 reaches a predeterminedposition corresponding to the second opening portion 53 b, the bentportion 54 b is restored in the bending direction and fitted into thelocking groove 42 a. As a result, the bent portion 54 b is locked in thelocking groove 42 a, and the adapter 50 is attached to the chuck jaw 39without falling off. In this way, the bent portion 54 b of the adapter50 functions as a locking portion lockable in the locking groove 42 a ofthe chuck jaw 39. When the adapter 50 is detached from the chuck jaw 39,the adapter 50 is displaced downward relative to the chuck jaw 39against the elastic force of the flat spring member 54. As a result, theengagement between the bent portion 54 b and the locking groove 42 a isforcibly released, and the adapter 50 is separated from the chuck jaw39.

As shown in FIGS. 18A and 18B, the adapter 50 includes an adapter 50 a(first adapter) having a flat clamping surface 81 clamping the body 31 aof the component 31 and an adapter 50 b (second adapter) having aholding groove 82 a holding the lead 3 d that is an axial portion of thecomponent 32. The clamping surface 81 is covered with an elastic memberso as to improve the clamping performance of the component 31. On theother hand, the holding groove 82 a is formed at the clamping surface 82of the adapter 50 b and the clamping surface 82 is made up of a metalmember so as to facilitate the formation of the holding groove 82 a. Theholding groove 82 a extends toward the tip of the adapter 50 b so as toguide the lead 3 d of the component 32 toward the substrate 2. Dependingon the shape of the lead 3 d of the component 32, the holding groove 82a can have a cross-sectional shape formed into various shapes by mixinglinear and curved portions. FIG. 19A shows the case that a lead 3 d 1 ofthe component 32 has a circular shape in a horizontal cross section. Inthis case, a holding groove 82 a 1 has a curved portion 82 b 1 holdingthe lead 3 d 1 in a horizontal cross section. FIG. 19B shows the casethat a lead 3 d 2 of the component 32 has a protruding portion 3 d 3protruding in the radial direction in a horizontal cross section. Inthis case, a holding groove 82 a 2 has a concave portion 82 b 2 holdingthe protruding portion 3 d 3 in a horizontal cross section so as to holdthe lead 3 d 2. FIG. 19C shows the case that a lead 3 d 4 of thecomponent 32 has a rectangular shape in a horizontal cross section. Inthis case, a holding groove 82 a 3 has a linear portion 82 b 3 holdingthe lead 3 d 4 in a horizontal cross section.

The clamping of the radial lead component by the adapters 50 is the sameas the clamping of the radial lead component by chuck jaws 39.Specifically, as shown in FIG. 20, the adapters 50 a respectivelyattached to a pair of the chuck jaws 39 move in directions approachingeach other from a state of enclosing the body 3 a of the component 31 onthe conveying chute 11 of the component supply unit 6 from both sides,thereby pinching and clamping the body 3 a of component 31. In this way,the adapter 50 a is detachably attached to the chuck jaw 39 (clampingmember) and clamps the component 31 in place of the chuck jaw 39. Theclamping surface 81 of the adapter 50 a is covered with the elasticmember (the sheet member 56). Subsequently, on the substrate 2, thepusher 44 is lowered to push the component 31 against the substrate 2.As a result, the component 31 is mounted on the substrate 2.

The clamping of the axial lead component by the adapters 50 is the sameas the clamping of the axial lead component by the chuck jaws 39.Specifically, as shown in FIG. 21, the adapters 50 b respectivelyattached to a pair of the chuck jaws 39 have a distance between theadapters 50 b set according to the interval between the leads 3 d of thecomponent 32 on the conveying chute 11. The chuck unit 25 is thenlowered toward the component 32. The component 32 is inserted betweenthe adapters 50 b and held such that the leads 32 d of the component 32are disposed along the holding groove 82 a, and the component 32 isclamped. Subsequently, on the substrate 2, the pusher 44 is lowered topush the component 32 against the substrate 2. As a result, thecomponent 32 is mounted on the substrate 2.

The adapter 50 is also used when a work object is the large-sizedcomponent 3 such as the component 3 that cannot stably be clamped by thechuck jaw 39, for example. Specifically, since the chuck jaw 39 isincorporated in the chuck unit 25, a replacement work of the chuck jaw39 requires a predetermined time and results in a large amount ofoperator's labor. Therefore, in this embodiment, the adapters 50 havingthe clamping surfaces 40 b corresponding to the size and shape of thecomponent 3 are attached to the chuck jaws 39 and the component 3 isclamped by using the adapters 50. Therefore, by attaching the adapters50 to the chuck jaws 39 depending on the component 3 to be mounted andclamping the component 3 by using the adapters 50, the clamping form ofthe component can easily be changed depending on the component 3 withoutthe need for the operator's replacement work. Additionally, by employinga configuration in which the adapter 50 is attached to or detached fromthe chuck jaw 39 by fitting the bent portion 54 b (the locking portion)into the locking groove 42 a or releasing the fitting of the bentportion 54 b into the locking groove 42 a, the attachment and detachmentof the adapter 50 is further facilitated.

The operator prepares the multiple adapters 50 having the clampingsurfaces 40 b corresponding to the shapes and sizes of the variouscomponents 3 at a production site. The adapters 50 suitable for thecomponent 3 are appropriately attached to the chuck jaws 39 to produce amounted substrate. By attaching the adapters 50 to the chuck jaws 39depending on the component 3 to be mounted and clamping and mounting thecomponent 3 by using the adapters 50 onto the substrate 2, flexibleproduction can be implemented according to various types of thecomponents 3.

The adapter stocker 20 will be described with reference to FIGS. 22A and22B. The adapter stocker 20 functions as a storage means storing theadapter 50. The adapter stocker 20 includes a storage block 60 supportedby the base 4 with support brackets 60 a. In the storage block 60,multiple (in this case, four) storage openings 60 b for storing andholding the adapters 50 in an upright posture are disposed in a latticearrangement. The storage openings 60 b each extend in the X directionsuch that a pair of the adapters 50 is stored and held. Therefore, theadapter stocker 20 of this example can store a total of four pairs ofthe adapters 50.

A length dimension R1 of the storage opening 60 b in the Y direction isset larger than a diameter dimension L1 of the block member 53 of theadapter 50 in the longitudinal direction shown in FIG. 14B and smallerthan a diameter dimension L2 of the flange part 51 of the adapter 50 inthe longitudinal direction shown in FIG. 14A. Therefore, in a state ofthe adapter 50 stored and held in the storage block 60, both endportions of the flange part 51 are in contact with an upper surface ofthe storage block 60 and the block member 53 is received in the storageopening 60 b (FIGS. 26A and 26B).

On the upper surface of the storage block 60, upward convex-shapedconvex portions 61 are disposed in pairs with the storage openings 60 binterposed therebetween in the Y direction. An interval between thepaired convex portions 61 is set to an interval corresponding to thenotch portions 51 a of the flange part 51. A thickness dimension of theconvex portions 61 is set to be smaller than a predetermined gap betweena locking plate 62 described later and the upper surface of the storageblock 60 and is set in this embodiment to be substantially the same as athickness dimension L3 of the flange part 51 shown in FIG. 14A. Byengaging the notch portions 51 a of the flange part 51 with the convexportions 61, the adapter 50 stored and held in the storage block 60 isfixedly positioned in the horizontal plane (FIG. 27). Therefore, theconvex portions 61 and the notch portions 51 a of the flange part 51serve as a storage position fixing means for fixing the storage positionof the adapter 50.

The locking plate 62 having a shape covering substantially the entirerange of the storage block 60 is disposed slidably in the horizontaldirection above the storage block 60 while maintaining a predeterminedgap with the upper surface of the storage block 60. One end portion ofthe locking plate 62 is coupled to a rod 63 a of a slide mechanism 63disposed on a lower surface of the storage block 60. The slide mechanism63 projects and retracts the rod 63 a through driving of a drive motor(not shown). As a result, the locking plate 62 reciprocates above thestorage block 60 (arrow h). The predetermined gap between the lockingplate 62 and the upper surface of the storage block 60 is set largerthan the thickness dimension L3 of the flange part 51 (FIG. 14A) and thethickness dimension of the convex portions 61 so as not to prevent thelocking plate 62 from sliding while the adapters 50 are stored and heldin the storage block 60.

The locking plate 62 has multiple opening portions 64 disposed atpositions corresponding to the arrangement of the multiple storageopenings 60 b. The opening portions 64 are each made up of multiple (inthis case, two) adapter insertion openings 64 a and a relief opening 64b penetrating the centers of the multiple adapter insertion openings 64a in the X direction, and these openings are continuously formed. Theadapter insertion openings 64 a have an opening width dimension R2 inthe Y direction set larger than the diameter dimension L2 (FIG. 14A) ofthe flange part 51 of the adapter 50 in the longitudinal direction andan opening dimension width R3 in the X direction set larger than adiameter dimension L4 of the flange part 51 in the width direction shownin FIG. 14A. Therefore, the adapter insertion openings 64 a are sizedsuch that the adapters 50 can be inserted in the vertical direction. Thetwo adapter insertion openings 64 a are arranged at an intervalcorresponding to the adapters 50 respectively attached to a pair of thechuck jaws 39, so that the adapters 50 attached to a pair of the chuckjaws 39 can be inserted at the same time.

The relief opening 64 b has a size capable of communicating with theopening portion 51 b of the flange part 51 in the vertical direction.Therefore, even if the locking plate 62 is slid in an arbitrarydirection, the opening portion 51 b of the flange part 51 of the adapter50 stored and held in the storage block 60 is always in communicationwith either the adapter insertion opening 64 a or the relief opening 64b in the vertical direction (FIGS. 23A, 23C). Therefore, even when thelocking plate 62 is moved in an arbitrary direction, the jaw portion 42of the chuck jaw 39 does not interfere with a body of the locking plate62 so that the jaw portion 42 can be inserted into and pulled out fromthe opening portion 51 b of the flange part 51.

A function of the locking plate 62 will be described with reference toFIGS. 23A to 23D. FIGS. 23A and 23B show a state in which two pairs ofthe adapters 50 are stored in the adapter stocker 20. The adapters 50are stored and held in the storage block 60 with the convex portions 61engaged with the notch portions 51 a of the flange part 51 and the blockmembers 53 received in the storage openings 60 b. In this state, thelocking plate 62 is at a position where the relief opening 64 b does notoverlap the flange part 51 in the vertical direction, and the adapterinsertion openings 64 a overlap the adapters 50 in the verticaldirection, so that the locking plate 62 does not inhibit the insertionof the adapters 50. Therefore, in this state, the already stored andheld adapters 50 can be taken out from the adapter stocker 20, and theadapters 50 can newly be stored and held in the empty storage openings60 b in which the adapters 50 are not stored.

FIGS. 23C and 23D show a state in which the sliding mechanism 63 isdriven to slide the locking plate 62 in a direction of an arrow i.Therefore, the locking plate 62 is moved by the driving of the slidemechanism 63 so that the body of the locking plate 62 verticallyoverlaps regions including both end portions of the flange part 51brought into contact with the upper surface of the storage block 60. Inthis state, the upward movement of the adapters 50 are restricted by thelocking plate 62. In other words, the adapters 50 are locked by thelocking plate 62 included in the adapter stocker 20. The openingportions 51 b of the flange parts 51 are still in communication with therelief openings 64 b in the vertical direction even when the lockingplate 62 is slid. Therefore, even when the adapters 50 are locked by thelocking plate 62, the adapters 50 can be attached to and detached fromthe chuck jaws 39.

A configuration of a control system of the component mounting device 1will be described with reference to FIG. 24. The control part 70included in the component mounting device 1 is configured to include astorage part 71, a mechanism driving part 72, and a recognitionprocessing part 73. The control part 70 is connected to a substrateconveying mechanism 5, the component supply unit 6, the X-axis beam 15,the plate member 16, the mounting head 17, the component recognitioncamera 19, the chuck driving motor 241, the chuck rotating motor 242,and the pusher actuator 45.

The storage part 71 stores various production data necessary formounting the component 3 on the substrate 2. The mechanism driving part72 is controlled by the control part 70 to drive the substrate conveyingmechanism 5, the component supply unit 6, the X-axis beam 15, the platemember 16, the mounting head 17, the component recognition camera 19,the chuck driving motor 241, the chuck rotating motor 242, and thepusher actuator 45. As a result, a component mounting work is performed.The mechanism driving part 72 also drives the X-axis beam 15, the platemember 16, the mounting head 17, the chuck driving motor 241, and thechuck rotating motor 242. As a result, a work for attaching/detachingthe adapter 50 to/from the chuck jaw 39 is performed. The chuck drivingmotor 241 and the chuck rotation motor 242 are preferably servo motors.Particularly, by using a servo motor for the chuck driving motor 241,switching can be made between a load control function of preferentiallycontrolling a clamping force of clamping the component 3 and a positioncontrol function of preferentially controlling an interval between thechuck jaws 39 or the adapters 50 b, depending on a type of the component3.

The recognition processing part 73 executes a recognition process of animage acquired by the component recognition camera 19 to detect asubstrate mark (not shown) formed on the substrate 2, the component 3supplied to a component supply position by the component supply unit 6,and the component 3 held by the mounting head 17. The detection resultsof the substrate mark and the component 3 are used when the mountinghead 17 is aligned with the substrate 2 at the time of mounting of thecomponent 3.

The component mounting device 1 in this embodiment is configured asdescribed above. An operation of attaching the adapter 50 to the chuckjaw 39 will be described with reference to FIGS. 25A to 25C. First, asshown in FIG. 25A, the unit head 17C is moved to above the adapterstocker 20, and a pair of the chuck jaws 39 is aligned above a pair ofthe adapters 50 to be mounted (ST1: alignment step). As shown in FIG.25B, the unit head 17C is then lowered to insert the jaw portions 42 ofthe chuck jaws 39 from the tips into the opening portions 51 b of theflange parts 51 (ST2: inserting step). Before executing (ST2), thelocking plate 62 is moved in advance such that the adapters 50 and theadapter insertion openings 64 a coincide with each other in the verticaldirection (FIGS. 23A and 23B).

Subsequently, at a predetermined timing in the process of allowing thejaw portions 42 of the chuck jaws 39 to pass through the first openingportions 53 a of the block members 53, the bent portions 54 b of theflat spring members 54 are fitted and locked into the locking grooves 42a of the jaw portions 42 (FIG. 17B). As a result, the adapters 50 areattached to the chuck jaws 39. As shown in FIG. 25C, the unit head 17Cis then raised to take out the adapters 50 attached to the chuck jaws 39from the adapter stocker 20.

In this way, in the present embodiment, the chuck jaws 39 are loweredfrom above the adapters 50 in the state of being stored in the adapterstocker 20 to insert the chuck jaws 39 into the opening portions (theopening portion 51 b, the first opening portion 53 a) and the adapters50 are thereby attached to the chuck jaws 39. Therefore, the clampingmembers (the chuck jaws 39, the adapters 50) can easily be switched in ashort time depending on a size of the component 3. Additionally, a pairof the adapters 50 can automatically be attached at the same time to thechuck jaws 39 without an operator's manual work.

An operation of detaching the adapter 50 attached to the chuck jaw 39will be described with reference to FIGS. 26A to 26C and 27. First, asshown in FIG. 26A, the unit head 17C is moved to above the adapterstocker 20, and a pair of the adapters 50 is aligned above the storageopenings 60 b that are storage destinations (ST11: alignment step). Asshown in FIG. 26B, the unit head 17C is then lowered so that the blockmembers 53 are received in the storage openings 60 b and that both endportions of the flange parts 51 are brought into contact with the uppersurface of the storage block 60. As a result, the adapters 50 are storedand held in the storage block 60 (ST22: storage step). In this state,the convex portions 61 are engaged with the notch portions 51 a of theflange parts 51 so that the positions of the adapters 50 are fixed inthe horizontal plane. Before executing (ST22), the locking plate 62 ismoved in advance such that the adapters 50 attached to the chuck jaws 39and the adapter insertion openings 64 a coincide with each other in thevertical direction (FIGS. 23A and 23B).

Subsequently, as shown in FIG. 26C, the locking plate 62 is slid (arrowj) to lock the stored and held adapters 50 (ST23: locking step) (seealso FIGS. 23C and 23D). As a result, the upward movement of theadapters 50 is restricted. As shown in FIG. 27, the unit head 17C israised to detach the adapters 50 from the chuck jaws 39 (ST24:detachment step). Specifically, in the process of raising the unit head17C, the flange parts 51 are brought into contact with the lower surfaceof the body of the locking plate 62 and prevented from moving upward.When the unit head 17C is further raised, the locked state between thebent portions 54 b and the locking grooves 42 a is forcibly released,and the adapters 50 are separated from the chuck jaws 39. As a result,the adapters 50 are automatically detached from the chuck jaws 39.

A method of mounting a component for mounting the component 3 suppliedby the parts feeder 10 onto the substrate 2 will be described. First,the control part 70 determines whether the component 3 to be mounted canbe clamped by the chuck jaws 39 (ST31: determination step). If it isdetermined at (ST31) that the component cannot be clamped, the controlpart 70 executes a process for attaching to the chuck jaws 39 theadapters 50 suitable for clamping the component 3 (ST32: clamping memberattachment step). Specifically, the unit head 17C accesses the adapterstocker 20. The chuck jaws 39 are lowered from above the adapters 50stored and held in the adapter stocker 20 to insert the chuck jaws 39into the opening portions and the adapters 50 are thereby attached tothe chuck jaw 39.

If it is determined at (ST31) that the component 3 to be mounted can beclamped by the chuck jaws 39, or after the adapters 50 are attached tothe chuck jaws 39 at (ST32), the mounting head 17 is moved to theposition of supply of the component 3 by the parts feeder 10.

If the component 3 is a radial lead component, the body 3 a of thecomponent 3 is disposed between the paired chuck jaws 39 or adapters 50a, and the paired chuck jaws 39 or adapters 50 a approach each other inthis state so as to clamp the body 3 a of the component 3 from thelateral sides (ST33 a: approaching step). The component 3 is thenclamped so as not to exceed a maximum value of the clamping force ofclamping the component 3 (ST34 a: clamping step). If the component 3 isan axial lead component, the distance between the paired chuck jaws 39or adapters 50 b is fixed to an inter-lead distance (ST33 b: intervalfixing step). The second component 32 is then inserted between thepaired chuck jaws 39 or adapters 50 b at the fixed interval, such thatthe second leads 32 d of the second component 32 are disposed along theholding grooves 40 c, 82 a (ST34 b: inserting step).

Subsequently, the mounting head 17 is moved to above the substrate 2preliminarily positioned at a predetermined work position. The unit head17C is then lowered so that the component 3 clamped by the chuck jaws 39or the adapters 50 is pushed by the pusher 44 and mounted on thesubstrate 2 (ST35: mounting step). Therefore, at this mounting step(ST35), the component 3 is clamped and mounted on the substrate 2 byusing the chuck jaws 39 or the adapters 50 attached to the chuck jaws39. As described above, according to this embodiment, the adapters 50suitable for clamping the component 3 are automatically attached to thechuck jaws 39 as needed and the component 3 is clamped and mounted onthe substrate 2 by using the adapters 50, so that the flexibleproduction can be implemented according to various types of thecomponents 3.

According to the component mounting device 1 having the configurationdescribed above, the following effects can be exerted.

The pair of the chuck jaws 39 is able to clamp both the first component3 including the first body 3 a and the first lead 3 b projectingdownward from the lower portion of the first body 3 a and the secondcomponent 32 including the second body 3 c and the second lead 3 dprojecting laterally from both side portions of the second body 3 c witha tip bent downward, and the pair of the chuck jaws 39 has facingportions each provided with the clamping surface 40 a contacting thefirst body 3 a of the first component 31 and the holding groove 40 cformed at the clamping surface 40 a and holding the second lead 3 d ofthe second component 32. Therefore, the clamping can be performed by thechuck jaws 39 in accordance with the shape of the component 3, and thefirst component 31 and the second component 32 can more reliably beclamped.

The holding groove 40 c extends toward the tip of the chuck jaw 39 toguide the second lead 3 d toward the substrate 2. Therefore, the secondcomponent 32 can easily be guided toward the substrate 2 while thesecond component 32 is clamped.

The control part 70 provides different control, i.e., control ofmanaging a clamping force, for example, control of managing a maximumvalue of the clamping force, or control of managing an interval of apair of the chuck jaws 39, depending on whether the chuck jaw 39 clampsthe first component 31 or the second component 32. Therefore, thecontrol of clamping corresponding to the shape of the component 3 can beprovided by the chuck jaws 39 so that the first component 31 and secondcomponent 32 can more reliably be clamped.

When the chuck jaws 39 clamp the first component 31, the control part 70provides control of managing the clamping force at which the pair of thechuck jaws 39 clamps the first component 31, for example, control ofmanaging the maximum value of the clamping force, and when the chuckjaws 39 clamp the second component 32, the control part 70 providescontrol of managing the interval of the pair of the chuck jaws 39 so asto fix the interval between the second leads 3 d held in the holdinggrooves 40 c. Therefore, the control of clamping corresponding to theshape of the component 3 can be provided by the chuck jaws 39 so thatthe first component 31 and second component 32 can more reliably beclamped.

The adapters 50 include the adapters 50 a each having the flat clampingsurface 81 clamping the first body 3 a of the first component 31 and theadapters 50 b each having the holding groove 82 a holding the lead 3 dthat is an axial portion of the second component 32. Therefore, theclamping corresponding to the shape of the component 3 can be performedby the adapters 50 so that the first component 31 and second component32 can more reliably be clamped.

The flat clamping surface 81 of the adapter 50 a is covered with anelastic member. Therefore, the adapters 50 a can easily clamp the body 3a of the first component 31.

The clamping surface 82 having the holding groove 82 a of the adapter 50b is made up of a metal member. Therefore, the holding groove 82 aholding the lead 3 d of the second component 32 can easily be formed.

The adapters 50 b include a plurality of types different incross-sectional shape of the holding groove 82 a corresponding to across-sectional shape of the lead 3 d. Therefore, the second components32 including the leads 3 d having various shapes can be clamped.

When the adapters 50 clamp the first component 31, the control part 70provides control of managing a clamping force at which the pair of theadapters 50 a clamps the first component 31, for example, control ofmanaging a maximum value of the clamping force, and when the adapters 50clamp the second component 32, the control part 70 provides control ofmanaging the interval of the pair of the adapters 50 b so as to fix theinterval between the second leads 3 d held in the holding grooves 82 a.Therefore, the control of clamping corresponding to the shape of thecomponent 3 can be provided by the adapters 50 so that the firstcomponent 31 and second component 32 can more reliably be clamped.

The component mounting device 1 in the present invention is not limitedto the embodiments described above and can be implemented withoutdeparting from the spirit of the present invention. For example, thechuck jaw 39 may be made up only of the jaw portion 42 without includingthe base portion 41 such that a predetermined position of the jawportion 42 is fixed by the jaw attachment seat 98 a, 98 b.

The present invention can provide the component mounting device capableof easily changing a clamping form depending on a component and themethod of mounting a component by using the component mounting deviceand is therefore particularly useful in the field of component mounting.
